Would it benefit me to switch to synthetic oil in my jeep's 4.7? Pros? Cons?

Thanks

Great idea. Better flow in cold temperatures, lower boil off rate when compared to conventional oils, more stable viscosity and capable of longer drain intervals between oil changes.

Up until about 90,000 miles I ran Ford Motorcraft Oil 10W40 in mine. When the price of gas jumped up I swapped over to Mobil 1 Full sythetic, that winter my 4.7 started to "tick" on cold starts. Once the oil pressure built up it went away. I went back to the Ford MotorCraft Synthetic Blend and have used it along with a WIX filter for a long time. Just recently I changed over to the new formula Rotella Oil.

I asked the same question when I switched to Mobil 1 Full synthetic, should I really have any problems? Other than a little bit of gas mileage increase I didn't really show much of an improvement. Although my WJ has a lot of miles (140,000) on it so take it for what its worth...
